To all whom #may concern:

Be it known that I, BERNDT W. BnooM- QUisT, a citizen of Finland, and a residentof Seattle, in the county of King and State of Washington, have 4invented certain new and useful Improvements in Emergency- Brakes for Ships, of which the following is -a full, true, and exact specification.

My invention relates to emergency brakes for ships and has for its principal object to provide a power operated apparatus of the above general description, which is adaptable to be mounted in a depression on the outside of a ship, for the purpose of assisting in quickly stopping or changing the course of a Ship.

A further object is to provide no vel and effective means for operating, securing and bracing the braking means. a

Other objects will appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawings and pointed out in the appended claim. i

In the drawings, Figure 1 is a side elevation of my device shown attached to a fragment of a ships side. Fig. 2 is a plan view taken along line ace-w of Fig. 1.

Referring more particularly to the drawings, numeral 1 designates a fragment of a ships side below the water line. Ribs 1a support the side 1. The side 1 is depressed inwardly as at 1b to provide a pocket o r depression to receive a wing 2 which 1s mounted upon a hinge pin 3 which pierces the side 1 above and below the depression 1h and takes bearing in bearings L1, which are secured to the side 1 on the inside. A longitudinally slotted bracket 5 is integral with the back of wing 2. A pin 6 secures one end of a piston rod 7 slidably with respect to wing 2, to said bracket 5. A piston head 8 is secured to the other end of piston rod 7 and operates slidably within a cylinder 9, which is supported on the inside of side 1 and on two of ribs 1a. It will be noted that piston rod 7 passes through the side 1, and that cylinder 9 makes a tight Joint with said side 1. Pipes 10 and 11 are connected one to either end of cylinder 9 for the purpose of supplying an operating fluid to the cylinder 9 from a source of power, not shown, and to convey the above mentioned fluid from the cylinder 9 after it has performed its function. Lugs 12 on the outside of wing 2 carry a pin 13 to which one end of a `compressionurod 14 is secured, the other end being secured to a pin 15 which is free to slide longitudinally in slots in ways 16 which are secured to side 1. Tie rods 17 pass through slots 18 in the forward end of wing 2 and are slidable in said slots. Enlarged ball ends 17a prevent rods 17 from pulling through slots 18. The opposite ends of rods 17 are secured to eye bolts 19 which are in turn secured to side The operation of my device is as follows: When the ship is under way and it is desired to stop or checkit or turn it sharply to one side or the other, it is only necessary to apply power to piston 8 through the 0perating medium which is admitted to pipe 10, which will force the forward end of wing 2 outward until beyond the outer line of the ship. As soon as the end of wing 2 is beyond said outer line, the force of the water will quickly throw the wing outward until brought to a stop by compression rod 141 whose outer end is brought up against the end of the slots in ways 16, and by tie rods 17 whose outer ends are brought up against the ends of slots 18. A ship may be equipped with a number of wings on each side, all or part of which may be operated at one time. If it is desired to change the ships course quickly only those on one side are used, while if it is desired to quickly stop the ship all will be used. After the ship is brought to a standstill, the wings are again drawn in by releasing the Huid from pipe 10 and applying to the piston 8 through pipe 11. My device may be hand operated for smaller boats, as the power required is slight. The necessity of some such device is apparent as it is often necessary to quickly stop a ship to prevent a collision.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein, will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described, except as defined in the appended claim. f

Having described my invention, what I claim as new and desire to protect by Let ters Patent, is`

In a control device for ships, the combination of a wing hinged to the side of the ship, the said side being provided with a recess into which the wing normally lits, a power operated piston secured-t0 the inside of the site end pivotally and slidably connected to ship and a sliding connection between the the ship and also tie rods which pass through 10 piston and the wing, whereby lwhen the pisslots in the wing.

ton is operated, one end of the wing is 5 thrown automatically from the ships side, BERNDT W' BLOOMQUIST' means for bracing the wing against the inerkinessem tia of the water, including a. rod having one R. D. SMALLEY, of its ends pivoted to the *wing and its oppo- VINIFRED KNOPH.
